'lNKlNG ATTACHMENT FOR EMBOSSlNGAND PRlNTlN G PRESSES.

SPECIFICATION forming part of Letters Patent No. 302,830, dated July 29.1884.

Application filed August 20,1883.

To all whom it may concern:

Be it known that I, HARMAN K. DRAW BAUGH, a citizen of the UnitedStates, residing at Harrisburg, in the county of Dauphin and State ofPennsylvania, have invented a new and useful Inking Attachment forEmbossing and Printing Presses, of which the following is such full,clear, and exact description as will enable those skilled in the art towhich it appertains to make and use the same by aid of the accompanyingdrawings.

My invention is applicable to several forms of popular embossing-pressesalready in use; and for illustration a Sanborn embossing-press 2peculiar cam on the inner face of main wheel,

it being composed of eccentric parts and a central concentric part withadjustably-mounted rock-shaft, adapted with wrist thereon to be actuatedby contact with said cam to receive rocking motion therefrom, withinking-rollers coupled by links with swinging arms on said shaft,whereby said rollers are reciprocated on guides to traverse thestationary form, and to pause intermittingly while on or in contact withthe constantly-rotating ink-distributing cylinder; second, the saidrock-shaft provided with crank and wrist, and arranged on supports uponthe machineframe to be at right angles to the face of main wheel, incombination with adjustable sleeve on said shaft, by adjusting which theshaft may be endwise shifted for gearing with said cam and disgearingtherefrom.

In the further description of my invention reference is had to theaccompanying drawings, in which Figurel represents a rear elevation of aSanborn embossing-press with my improved inking attachment thereon. Fig.2 represents a side elevation of the same with fly-wheel and pulleysremoved. Fig. 3 repis shown in the drawings with my inking at- (Nomodel.)

resents the master-wheel with double cam thereon, and rockshaft with itsconnections in retracted position. Fig. 4 represents said wheel, cam,and rock-shaft in advanced position, as when engaged in the act ofinking. 5.5 Fig. 5 represents an elevation of the rock-shaft with crankand anti-friction roller on its wrist. Fig. 6 represents the said wristpin or stud and the anti-friction roller. Fig. 7 represents an end viewof one of the slides carrying the inking-rollers. Fig. 8 represents oneof the adjustable bearing-blocks on said slides. Fig.

9 represents a perspective view of one of the adjustable slides for theinking-rollers aforesaid.

Similar reference-letters denote si milar parts throughout the severalviews.

Letter A denotes the front end of said press,

A the rear end of the same.

B denotes the flywheel; C G, the driver and the idle pulley,respectively C, the exterior support for shaft D, having said wheel andpulleys thereon, as shown, and on its inner end said shaft has on it thepinion 6*, (shown in dotted lines,) which drives the mas- 7 5 ter-wheelM, which latter moves the shaft M, and the eccentric O thereon, whichlatter works the compound toggles V WV WY W and thereby actuates theplaten X, in the usual manner.

Z denotes atreadle; Z a stop therefor, and Z,the link connecting treadleand toggle-beam WW, whereby the motion of the levers may be interruptedin the usual way.

Pdenotes thepress-receiver; P", curbs there- 85 for.

N denotes the press-head, and Z steam-fittings for heating the same bycommunication of its interior with a boiler.

N denotes a form or plate.

The master-wheel M has on its disk or inner face the double cam Q Q,which, in conjunction with the wheel-hub M operates the inkingattachments, combined and arranged therewith in a novel manner. Saidwheel, 5 when newly made, can have my said improved cam cast thereonwith very little additional cost and no additional labor.

For refitting presses already extant, the camsections Q and Q may bebolted or riveted to I00 the wheel, its face being deeply recessedbetween its rim and hub, the sections Q and Q: being abutted thereto.

The travel of the anti-frictional wrist g g is as follows: Starting atthe most eccentric point in the cam against the rim Q with the wheelM'rotated in the direction denoted by the arrow, said wrist is engagedby the concave side of cam-section Q, and thereby guided centerwarduntil it arrives at the hub M and stands against it while saidcam-section Q passes it or rotates onthat is, it stands still bearingagainst said hub for about one-third of a revolution of the wheel M. Theposition of the levers ofthe apparatus is such now that they act bygravity to keep said wrist in said position, as shown in Fig. 3. On thefurther rtation of said wheel the cam-section Q engages said wrist bycontact with its convex side, and thereby guides the same eccentricallyuntil it is deflected nearly to the rim Q whereat, by a cut or pathbetween said cainsections Q Q or their equivalent, the said wristarrives again at the starting-point, from which its travel wastracedthat is, at its initial point against section Q. The inclinationof the levers of the apparatus is now such that they act by gravity tokeep said wrist pressed against section Q. The deflections of the crankE by said wrist g g, guided by cam Q Q, as described, cause the shaft S"to rock and the arms L L thereon to oscillate, said arms being pivotedat their ends to links K K,which latter are pivoted at their other endsto slides "m. on the guides it, pass said slides back and forth, andlikewise the inking-rollers H H supported thereon. Said reciprocatorylIlO- tion of said slides and rollers is rectilinear; but

, said rollers also are rotated by circumferential contact with theink-distributing cylinder G, which is driven by a belt, F, connectingits pulley twith shaft D. Said rollers H H dwell on or against saidcylinder in the intervals of pressing or rest from their transversemotion. Said transverse movement may be varied by adjusting the stud gin a slot in the crank E, thus varying its radius and consequently itsthrow and that of the arms L L". The inkdistributing cylinder G ismounted rearward from the press-bed to allow the cylinder to be adjustedrearward unobstructedly for large work. The rock-shaft S is locatedrearward still farther to be out of the way of said cylinder, and todeliver inking-rollers H H to dwell thereon. Said shaft has the twosupports'S and T. Said support S is a post erected on rail Y, as shown;but in new presses the cap 12 of shaft M may be prolonged to supportsaid shaft Si thereon. The post shown is designed for refitting machinesalready in use. The other bearing of said shaft S is, in the support T,arranged inward from the end, having the crank E'thereon, as shown inFig. 1, so that the arm L on said shaft, as arranged between said crankE and said support T, may leave surplus space between its socket L andsaid support to allow the shaft S to be shifted away 7 from the wheel Msufficiently to disgear the wrist g g from the cam-sections Q Q whenembossing or smashing only is to be done on the press.

The act of disgearing is more particularly provided for as follows: Onshaft S are two sleeves, R R, arranged directly inside of the supports Sand T, respectively. The same are held in place by set-screws. When thesetscrew of sleeve R is slacked the sleevemay be slipped farther inwardfrom the said support S, and the shaft itself may then be slipped orshifted at its bearings freely, the said sleeves being the only keepersfor said shaft longitudinally; hence, said wrist may be disgeared atwill, and the inking attachment will be suspended for running theembossing-machine distinctly therefrom. The arms L L are attached to theshaft S by sockets or butts L, with set-screws, as shown in Fig. 1. Thearm L is direct, and arm L is offset to vibrate free of wheel M, andcarry its connecting-link K parallel with link K. The links K K arepivoted at their ends similarly, respectively, to the arms L L and tothe slides m, being joined to the latter at K on their inner sides andcentrally opposite the guideways therein.- The slides are entered onguides 7c, which pass through. the ways J in the same. Said guides aresupported in horizontal and parallel direction on the jambs in theopening in the arch or uprights A,to which latter they are attached bybraces h bolted to them and to said jambs, as shown. The said braces hare of narrower bar than the guides k, that they may let pass the slidesm cut open at J for this purpose. Each of said slides m hasvertically-adj ustable bearings h h, or block f connected with it bydove tail joint, and by a screw, (1, traveling in an extension, r, onsaid block f, and swiveled in the extension q, and thereby raising orlower-- ing said block, and thereby also raising or lowering theinking-rollers H H- supported in said bearings h h. The inking-cylinderGis mounted on supports P P, as shown. The

nuts or screws for securing the cap on the journals of shaft D may alsosecure said supports at the same time. Said cylinder Gis of sufficientdiameter to afford ample distributing-surface thereon. The same isarranged parallel with and has circumferential contact with theinking-rollers H H, which latter dwell on it and areset in motion bycontact therewith during about one-third of each revolution of the wheelM, while the cam-sections Q Q are intermittent or inoperative. Thecylinder may be supplied with ink manually in the usual way; or it maycommunicate with a duck-roller in a fountain in any well-known orapproved way. The inkingrollersH H may be adjusted vertically by thescrews (Z to bear against forms or dies for embossed work of varyingheights or inclinations. The inking-rollers H H have their journalssupported in open bearings h h provided with keepers therefor, that theymay be readily removed for repairs or dressing.

I am aware that my inking attachment may be embodied in the make up ofnew embossing-presses resembling the one shown in the drawings in theparticular of having a master-wheel making one revolution to eachadvance of the press-platen, and having the same somewhat remote fromsaid platen or from the press-h ead, as in such the cam-sections Q Q canbe readily added with little added cost, and the rock-shaft supports canbe made modifications of the masterwheel journal-cap, and an arm on therear end, A, of the press-frame.

I do not,therefore,confine this application to the refitting of old andvaluable machines, but intend to embrace and cover by it new machines,employing some or all of its new and useful features for the purpose ofmaking combination embossing and printing machines adapted for eitheroperation distinctly or for both conjointly.

WVhat I claim is 1. In an embossing and printing press, the combinationof the cam on disk of main wheel M, having the eccentric parts QQand thecentral concentricpart, M with the adjustablyequipped rock-shaft S R LL", in communica tion with said cam by wrist g g, and with theinking-rollers'H H. by links K K, pivoted to slides m, supporting them,all co-operating to impart to said rollers extensive reciprocatorymovements to traverse the stationary form N and to cause them topauseintermittingly while on the constantly-rotating cylinder G,substantially as and for the purposes set forth.

2. The rock-shaft S, provided with crank E and wrist g g, and mounted inbearings on supports S T, and presented thereby to gear with anactuating-cam on the face of the wheel M, in combination with asleeve,R, secured on said shaft by a set-screw, by adjusting which saidrock-shaft may be shifted and disgeared with said wheel and its cam,substantially as and for the purposes set forth.

3. The combination of the actuating-cam Q Q on wheel M, the rock-shaftS, provided with means E y g, for connecting with said cam, theadjustable sleeve R on the said shaft for disgearing it with said camand supporting it when geared therewith, the arms L L on said shaft, thelinks K K, guides 7r, slides m, and inking-rollers H H, all co-operatingto cause the latter to travel over the form under the press-l1ead and toreturn to pause while over and in communication with theink-distributing cylinder G, substantially as set forth.
